Alvord Lake is a seasonal, alkali lake. The Alvord Lake playa is bounded by Steens Mountains to the west, the Alvord
Desert to the north and east, has a northern edge 3.8 miles south of Andrews,
Oregon, and is about 8 miles north of Fields, Oregon. The playa is approximately 4 miles long and one and 3/4 miles wide. The Alvord margins are defined by wet meadows and salt desert vegetation on the west, and dunes and salt desert vegetation on the east. Waters from Wildhorse Creek and other streams flowing from the east side of Steens Mountain occasionally feed into Alvord Lake, as does the ouflow from Borax Lake on the SE and Trout Creek on the east. Most of the immediate area draining into Alvord Lake from the south is charachterized by white, crusty, highly alkaline soils.
This IBA includes Alvord Lake and an as of yet undefined extent of the Alvord Basin.
